Spectral Analysis of Narrow Band Periodic Signals

Abstract:

The possibility of using lattice periodic functions in the processing of narrowband signals with methods of discrete Fourier transform, instantaneous spectral density, and synchronous detection providing reduction of the number of readouts being processed, is shown. Results of the method’s experimental evaluation are considered. Suggested method can be used for increasing efficiency of correlation analysis of narrow band signals and for precise measuring of mains electricity supply frequency.
